  However, in the case of the anaglyph method, there is a problem that a color image cannot be displayed to an observer because complementary color glasses are used.

  Further, in the stereoscopic image display devices described in Patent Document 1 and Patent Document 2, a stereo image, that is, a right-eye image and a left-eye image are displayed on a color liquid crystal plate as an image to be observed by an observer. Since the images are displayed in a time-sharing manner, it is necessary to send two images, one for the right eye and one for the left eye, to the color liquid crystal plate with respect to the same image. there were.

  In the stereoscopic image display devices described in Patent Document 1 and Patent Document 2, a stereo image, that is, a right-eye image and a left-eye image are color images each composed of three colors of RGB. 3D image display device of an unconventional method different from this method, which distributes the color image for the right eye to the right eye and distributes the color image for the left eye to the left eye Was desired.

  Therefore, the present invention can display a color image to an observer even in an anaglyph method, and can reduce the amount of data to be transmitted to a display device when displaying a stereoscopic image. It is an object of the present invention to provide a stereoscopic image display apparatus.

  The present invention was created in order to solve the above-described problems. First, the stereoscopic image display device is a right-eye video signal, and any one of the three types of RGB signals.

The light distribution means distributes the first video signal and the third video signal to the right eye of the observer and distributes the second video signal and the third video signal to the left eye of the observer. Since the one video signal, the third video signal, and the second video signal are three consecutive parallax images, a stereoscopic color video can be displayed to the observer. As described above, a stereoscopic color image can be displayed by a method that has not been used in the past. In addition, since the data amount of each signal to be displayed is only composed of RGB signals in one frame image, it is the same as the normal data amount for one frame, and data to be transmitted to the display device. The amount can be reduced.

  Second, in the first configuration, the video signal output means captures the right-eye video to obtain the first video signal, and the left-eye A second photographing device for photographing a video to obtain a second video signal, and a third photographing device for photographing a parallax image intermediate between the first video signal and the second video signal to obtain a third video signal It is characterized by having. With these three photographing devices, three consecutive parallax images can be obtained.

  Third, in the first configuration, the video signal output means reproduces and outputs the first video signal, the second video signal, and the third video signal recorded on the recording medium. Features.

  In the fourth configuration, by generating an intermediate image video signal from the right-eye RGB video signal and the left-eye RGB video signal, three consecutive parallax images are obtained. There is no need to shoot a parallax image, and in particular, it is possible to display a stereoscopic image using a so-called stereo image that has been conventionally used.

  Fifth, in the fourth configuration, the intermediate image generation unit generates a morphing image of a right-eye video and a left-eye video to generate an intermediate image.

  In the fourth and fifth configurations, the third video signal is generated from the first video signal and the second video signal recorded on the recording medium, or the input first video signal and the second video are input.

On the other hand, since the blue filter transmits not only blue light (B signal image) but also green light (G signal component), it distributes the other of the first video signal and the second video signal and the third video signal. Thus, it is possible to display a stereoscopic image to the observer. In particular, since red light, blue light, and green light can be distributed to the observer, a stereoscopic image can be displayed as a color image even when complementary color glasses are used.

Blue light and green light are distributed among the color images. On the other hand, the color image displayed on the display means is displayed on the left eye of the observer with the backlight of red light and green light as the background. Red light and green light are distributed in the image.

The light distribution device distributes the first video signal and the third video signal to the right eye of the observer and distributes the second video signal and the third video signal to the left eye of the observer. Since the one video signal, the third video signal, and the second video signal are three consecutive parallax images, a stereoscopic color video can be displayed to the observer. As described above, a stereoscopic color image can be displayed by a method that has not been used in the past. In addition, since the data amount of each signal to be displayed is only composed of RGB signals in one frame image, it is the same as the normal data amount for one frame, and data to be transmitted to the display device.

The distance P2 between the center position 14a and the distance P3 between the center position 14a and the center position 16a is configured to be equal or substantially equal. Further, the distance P1 between the center position 12a and the center position 16a is substantially equal to the distance between the human eyes. Thereby, it can be said that the video image | photographed with the imaging devices 12-16 is three continuous parallax images.

Yes.

  Further, the display control device 20 receives each signal from the imaging devices 12 to 16 and displays the signal on the display device 30. That is, the video signal for each frame sent from the imaging devices 12 to 16 is displayed in a matrix for each pixel. That is, the display control device 20 has a matrix circuit function. Specifically, the display control device 20 performs display control of the B signal for each pixel in the display device 30 according to the B signal from the imaging device 12, and each display in the display device 30 according to the G signal from the imaging device 14. Display control of the G signal is performed for each pixel, and display control of the R signal is performed for each pixel in the display device 30 according to the R signal from the imaging device 16.

  Further, the display device 30 is a display device that displays a color image, and is configured to display an R signal, a G signal, and a B signal for each pixel 32 as shown in FIG. The photographing system 10 and the display control device 20 constitute a video signal output unit and a video signal output device.

  The complementary color glasses 40 have filters of different colors, specifically, a red filter and a blue filter. For example, as shown in FIG. 4, a red filter 42 is provided on the left eye side, and a blue filter 44 is provided on the right eye side. The red filter 42 is composed of a red translucent member, and the blue filter 44 is composed of a blue translucent member. A red filter may be used on the right eye side and a blue filter may be used on the left eye side.

  Here, the red filter and the blue filter will be described. As shown in FIG. 5, the red filter transmits red light but also transmits green light. The blue filter transmits blue light but transmits green light. Is also transparent. Therefore, by applying the complementary color glasses 40, the red filter 42 transmits red light and green light, so that the R signal and G signal can be seen by the left eye, and the blue filter 44 is blue light and green light. Therefore, the B signal and the G signal can be seen by the right eye.

  The operation of the stereoscopic video display apparatus 1 having the above configuration will be described. The imaging system 10 captures an object (imaging process) and outputs a predetermined video signal. That is, the photographing device 12 outputs a B signal, the photographing device 14 outputs a G signal, and the photographing device 16 outputs an R signal.

  Then, the display control device 20 controls the display of the signal sent from each imaging device for each pixel and outputs it to the display device 30 (video signal output step). Thereby, each signal is displayed on the display device 30 (display process). The video displayed on the display device 30 is a color video composed of a B signal, a G signal, and an R signal, but the B signal, that is, the blue light is a video shot from the direction of the photographing device 12, and the G signal, That is, the green light is an image taken from the direction of the photographing device 14, and the R signal, that is, the red light is an image taken from the direction of the photographing device 16. Here, in the above example, the B signal corresponds to the first video signal, the R signal corresponds to the second video signal, and the G signal corresponds to the third video signal.

  When the viewer visually recognizes the image displayed on the display device 30 through the complementary color glasses 40 having the above-described configuration, the R signal and the G signal are distributed to the left eye, and the B signal and the G signal are transmitted to the right eye. Since the signal is distributed (light distribution process), the R and G signals can be seen by the left eye, and the B and G signals can be seen by the right eye. Therefore, the subject photographed from the direction of the photographing device 12, the subject photographed from the direction of the photographing device 14, and the subject photographed from the direction of the photographing device 16 can be seen, and thus a stereoscopic image can be displayed.

  As described above, in the stereoscopic image display apparatus 1 according to the present embodiment, as shown in FIG. 6, a right-eye image composed of blue (that is, a B signal image) and a left composed of red. In three consecutive parallax images composed of an eye image (that is, an R signal image) and an intermediate image composed of green (that is, an G signal image), a right eye image and an intermediate image Is distributed to the right eye, and a left-eye image and an intermediate image are distributed to the left eye, thereby displaying a stereoscopic image. That is, the stereoscopic image display apparatus according to the present embodiment includes three consecutive parallax images composed of only three different primary colors, a first image (for example, a B signal (right eye image)) and a second image. Three images (intermediate video) and a third image (for example, an R signal (video for the left eye)), and the second image is located between the first image and the third image. In a parallax image, one of the first image and the third image is distributed to the right eye, the other is distributed to the left eye, and the second image is distributed to both the right eye and the left eye You can say that.

  In the above description, the imaging device 12 outputs the B signal and the imaging device 16 outputs the R signal. However, in reverse, the imaging device 12 outputs the R signal to capture the image. The device 16 may output the B signal.

  In the above configuration, the video shot by the shooting system 10 has been described as being displayed on the display device 30 by the display control device 20, but the video shot by the shooting system 10 is recorded on a recording medium, and this recording is performed. The video information recorded on the medium may be played back by a playback device having the function of the display control device 20. That is, it is possible to display a stereoscopic video by recording the B signal, the G signal, and the R signal for each frame constituting the moving image and reproducing each signal by the reproduction device.

  Next, a stereoscopic video display apparatus according to Embodiment 2 of the present invention will be described. A stereoscopic image display device 50 according to the second embodiment is configured as illustrated in FIG. 7, and includes a photographing system 60, a display control device 70, a display device 80, a light source 100, and a large convex lens (imaging unit, imaging device). ) 110, mirror 120, diffuser 130, infrared camera 140, display control device (display control means, display control device) 150, and backlight light source (backlight means, backlight device) 160. ing.

  Here, the photographing system 60 has the same configuration as the photographing system 10 described above, and the photographing system 60 includes a photographing device 62, a photographing device 64, and a photographing device 66. Each of the photographing devices in the photographing devices 62, 64, and 66 is a device that captures a color image of a moving image. One photographing device in the photographing devices 62, 64, and 66 (hereinafter referred to as photographing devices 62 to 66) is an RGB signal. The imaging device 62 outputs one signal in the RGB signal, the imaging device 64 outputs one of the remaining two signals in the RGB signal, and the imaging device 66 outputs the remaining one of the RGB signals.

  Specifically, the imaging device 62 outputs a B signal in the RGB signal, the imaging device 64 outputs a G signal in the RGB signal, and the imaging device 66 outputs an R signal in the RGB signal. Specifically, for example, since the CCD camera is provided with an output terminal so that any one of the RGB signals can be individually output, it may be output from a predetermined output terminal. That is, the imaging devices 62 to 66 output a video signal for each frame, and the video signal of a certain frame is composed of a signal for each pixel. In general, since the video signal is composed of digital signals, the B signal, G signal, and R signal are composed of binary signals for each pixel. It should be noted that the image capturing device 62, the image capturing device 64, and the image capturing device 66 naturally operate synchronously, and the image signals captured and output by the image capturing devices 62 to 64 are image signals at the same timing.

  Further, the positional relationship among the imaging device 62, the imaging device 64, and the imaging device 66 is the same as in the case of the first embodiment, and as shown in FIGS. 1 and 2, the imaging device 64 has an imaging function with the imaging device 62. Provided at a position between the devices 66, the photographing device 62 and the photographing device 66 have their installation positions and photographing directions at the time of photographing so that a stereo image can be obtained when a human visually recognizes an object. ing. That is, the center position 64a of the photographing lens of the photographing device 64 is located at or near a straight line connecting the central position 62a of the photographing lens of the photographing device 62 and the central position 66a of the photographing lens of the photographing device 66, and the central position 62a. The distance P2 between the center position 64a and the distance P3 between the center position 64a and the center position 66a are configured to be equal or substantially equal. The distance P1 between the center position 62a and the center position 66a is substantially equal to the distance between both eyes of the human. Thereby, it can be said that the image | video image | photographed with the imaging devices 62-66 is three continuous parallax images. Further, it can be said that the video obtained by the photographing device 62 is a right-eye video, the video obtained by the photographing device 66 is a left-eye video, and the video obtained by the photographing device 64 is an intermediate video.

  Note that the photographing device 62, the photographing device 64, and the photographing device 66 are configured to photograph the same object. For example, when photographing a subject with the photographing device 62, the orientation and the focal length of the photographing device 64 and the photographing device 66 are automatically set based on the orientation and focal length of the photographing lens of the photographing device 62. Yes.

  In the above description, the imaging device 62 outputs the B signal, the imaging device 64 outputs the G signal, and the imaging device 66 outputs the R signal. However, the imaging device 62 outputs 1 signal in the RGB signal. Any one may be used as long as it outputs one signal, the photographing device 64 outputs one of the remaining two signals in the RGB signal, and the photographing device 66 outputs the remaining one signal in the RGB signal. Therefore, there are six types of combinations. That is, when the right-eye video signal is the B signal, the intermediate video signal is the G signal, and the left-eye video signal is the R signal (this is the case described above), the right-eye video signal is the B signal. When the intermediate video signal is an R signal and the left eye video signal is a G signal, the right eye video signal is a G signal, the intermediate video signal is a B signal, and the left eye video signal is an R signal. The right-eye video signal is a G signal, the intermediate video signal is an R signal, and the left-eye video signal is a B signal, and the right-eye video signal is an R signal and the intermediate video signal is a B signal. In some cases, the left-eye video signal is a G signal, the right-eye video signal is an R signal, the intermediate video signal is a G signal, and the left-eye video signal is a B signal.

  Further, the display control device 70 receives each signal from the photographing devices 62 to 66 and displays the signal on the display device 80. That is, the video signal for each frame sent from the imaging devices 62 to 66 is displayed in a matrix for each pixel. That is, the display control device 70 has a function of a matrix circuit. Specifically, the display control device 70 performs display control of the B signal for each pixel in the display device 80 in accordance with the B signal from the imaging device 62, and each display in the display device 80 in accordance with the G signal from the imaging device 64. Display control of the G signal is performed for each pixel, and display control of the R signal is performed for each pixel in the display device 80 in accordance with the R signal from the imaging device 66.

  The display device 80 is a transmissive color video display device, specifically a transmissive color liquid crystal television. The display device 80 can be said to be obtained by omitting the backlight configuration from a normal color liquid crystal television, and the image displayed on the display device 80 is displayed on the viewer side by the light from the backlight light source 160. . The display device 80 displays RGB signals sent from the display control device 70, and is configured to display an R signal, a G signal, and a B signal for each pixel 82 (FIG. 3). reference).

  The light source 100 is an infrared light source, and is provided so as to irradiate the observer with infrared light from one of the left and right directions of the display device 80. That is, the light source 100 is configured to irradiate infrared light from an oblique front of an observer who visually recognizes the display device 80. The light source 100 may be irradiated from the side, that is, the direction perpendicular to the direction of the display device 80 and from the direction perpendicular to the direction of the display device 80, that is, from the side of the observer. . In other words, the irradiation direction of the infrared ray of the light source 100 may be a position where a half-view image of the observer can be obtained, and any direction from an oblique direction to a side with respect to the display surface of the display device 80. It may be a position.

  The large convex lens 110 is provided behind the display device 80, and is used to enlarge and display the image displayed on the backlight light source 160 to the observer. The large convex lens 110 may be other imaging means such as a Fresnel convex lens, a diffraction grating lens, a convex lens array, a Fresnel lens array, or a diffraction grating lens array instead of the convex lens.

  The mirror 120 is a half mirror that reflects an observer image, which is an image of an observer located in front of the display device 80, toward the infrared camera 140, and forwards the image displayed on the backlight light source 160 to the front. That is, it has a function of displaying to an observer positioned in front of the display device 80.

  The diffuser 130 is for diffusing the infrared light image of the observer reflected from the mirror 120.

  The infrared camera 140 is a camera for inputting an infrared light image of an observer reflected by the mirror 120. That is, the infrared camera 140 is configured so that an observer's infrared light image obtained by irradiating an observer with infrared rays from a light source (that is, an infrared light image of a half-surface image of the observer) is mirrored through the large convex lens 110. Since it is reflected downward by 120, the reflected infrared light image is input and an infrared light video signal is output to the display control device 150. In addition, when a change occurs in the optical intensity of the infrared light image of the observer due to the image input to the display device 80, in accordance with the luminance signal in the signal sent from the display control device 70 in order to correct this. Thus, it is preferable to automatically adjust the aperture of the optical aperture of the infrared camera 140. That is, a signal sent from the display control device 70 to the display device 80 is also input to the infrared camera 140, and the infrared camera 140 automatically adjusts the aperture of the optical aperture of the infrared camera 140 according to the luminance signal in this signal. Note that at least the light source 100, the mirror 120, and the infrared camera 140 constitute the imaging means and the imaging device.

  In addition, the display control device 150 performs display control of the backlight light source 160 in accordance with the infrared video signal sent from the infrared camera 140. That is, since the half-view image of the observer is obtained by the infrared light video signal sent from the infrared camera 140, the display control device 150 binarizes the infrared light video signal to generate a binary image, This binarized image is displayed in a predetermined region in the backlight light source, that is, in a region geometrically coincident with the region in which the observer image is focused on the backlight light source side by the large convex lens 110. When displaying this binarized image, two predetermined signals in RGB are displayed. In this way, one binarized image is displayed. At the same time, based on the binarized image obtained from the above infrared light image signal, a binarized image of the other half-surface image that is symmetrical to the binarized image is generated, and the other binarized image is generated. The binarized image is also displayed at a position symmetrical to the area where the one binarized image is displayed. For example, as shown in FIGS. 7 and 8, when the light source 100 is provided on the right side of the observer and an infrared light image signal on the right side of the observer is obtained, the other binary image J2 is The one binarized image is displayed on the right side as viewed from the observer (see FIG. 9). The one binarized image J1 is displayed on the left side of the other binarized image J2. That is, when viewed from the observer, one binarized image J1 is displayed on the left side, and the other binarized image J2 is displayed on the right side adjacent to the binarized image J1. This binarized image J1 is a binarized image for the right eye, and the binarized image J2 is a binarized image for the left eye. When displaying this binarized image, two predetermined signals in RGB are displayed.

  The predetermined two signals for displaying the binarized image are determined according to three consecutive parallax images photographed by the photographing system 60. That is, for a binarized image that enters the right eye of the observer, a signal corresponding to the right eye image and a signal corresponding to the intermediate image in the imaging system are displayed, and the binarized image that enters the left eye of the observer Is displayed with a signal corresponding to the image for the left eye in the photographing system and a signal corresponding to the intermediate image.

  For example, when the right-eye video is a B signal, the intermediate video is a G signal, and the left-eye signal is an R signal, the B signal and the G signal are displayed in one binary image J1. That is, only the B signal and the G signal are displayed at each pixel in the display area of the binarized image J1, and the R signal and the G signal are displayed on the other binarized image J2. That is, only the R signal and the G signal are displayed at each pixel in the display area of the binarized image J2.

  The backlight light source 160 is a display device that displays a color image, and performs RGB output in accordance with display control by the display control device 150. That is, a color image is displayed according to the R signal, the G signal, and the B signal from the display control device 150.

  The imaging system 60 and the display control device 70 constitute the video signal output means and the video signal output device. Further, the light source 100, the large convex lens 110, the mirror 120, the diffuser 130, the infrared camera 140, the display control device 150, and the backlight light source 160 constitute the light distribution means and the light distribution device.

  In the stereoscopic image display device 50 according to the second embodiment, unlike the first embodiment, the complementary color glasses are not used.

  The operation of the stereoscopic video display device 50 having the above configuration will be described. The photographing system 60 photographs a subject and outputs a predetermined video signal. That is, the photographing device 62 outputs a B signal, the photographing device 64 outputs a G signal, and the photographing device 66 outputs an R signal.

  Then, the display control device 70 performs display control for each pixel and outputs the signal output from each imaging device to the display device 80 (video signal output step). Thereby, each signal is displayed on the display device 80 (display process). The video displayed on the display device 80 is a color video composed of a B signal, a G signal, and an R signal, but the B signal, that is, the blue light is a video shot from the direction of the photographing device 62, and the G signal, That is, the green light is an image taken from the direction of the photographing device 64, and the R signal, that is, the red light is an image taken from the direction of the photographing device 66. Here, in the above example, the B signal corresponds to the first video signal, the R signal corresponds to the second video signal, and the G signal corresponds to the third video signal.

  On the other hand, when an infrared ray is irradiated from the light source 100 to the observer, the infrared light image of the observer (that is, the infrared light image of the half-surface image of the observer) passes through the large convex lens 110 and is reflected by the mirror 120. The reflected image is captured by the infrared camera 140.

  Then, the infrared camera 140 outputs an infrared light video signal to the display control device 150 based on the captured infrared light image, and the display control device 150 returns a backlight based on the infrared light image sent from the infrared camera 140. Display control of the light source 160 is performed. That is, since the half-view image of the observer is obtained by the infrared light video signal sent from the infrared camera 140, the display control device 150 binarizes the infrared light video signal to generate a binary image, This binarized image J1 is displayed in a predetermined region in the backlight source, that is, in a region that geometrically coincides with the region in which the observer image is focused on the backlight source side by the large convex lens 110. When displaying the binarized image J1, two predetermined signals in RGB are displayed, and a signal corresponding to the right-eye image and a signal corresponding to the intermediate image are displayed. For example, when the video signal for the right eye is a B signal, the intermediate video signal is a G signal, and the video signal for the left eye is an R signal, the B signal and the G signal are displayed for the display area of the binary image J1. Display for each pixel.

  At the same time, based on the binarized image obtained from the above infrared light image signal, a binarized image of the other half-surface image that is symmetrical to the binarized image is generated, and the other binarized image is generated. The binarized image is also displayed at a position symmetrical to the area where the one binarized image is displayed. For example, as shown in FIGS. 7 and 8, when the light source 100 is provided on the right side of the observer and an infrared light image signal on the right side of the observer is obtained, the other binary image J2 is The one binarized image is displayed on the right side as viewed from the observer (see FIG. 9). When displaying the binarized image J2, two predetermined signals in RGB are displayed, and a signal corresponding to the image for the left eye and a signal corresponding to the intermediate image are displayed. For example, when the video signal for the right eye is a B signal, the intermediate video signal is a G signal, and the video signal for the left eye is an R signal, the R signal and the G signal are displayed for the display area of the binary image J2. Display for each pixel.

  Then, since the color image displayed on the display device 80 is visually recognized through the display by the B signal and the G signal, that is, the blue and green backlights, to the right eye of the observer, Only the B signal image and the G signal image in the color image displayed on the display device 80 are distributed (light distribution process), and thus only the blue image and the green image in the color image displayed on the display device 80 are distributed. On the other hand, on the left eye of the observer, the color image displayed on the display device 80 is visually recognized through the display by the R signal and the G signal, that is, the red and green image backlights. Therefore, only the R signal image and the G signal image in the color image displayed on the display device 80 are distributed to the left eye (light distribution process), and thus the color image displayed on the display device 80 is displayed. It can be visually recognized only definitive red image and green image. Accordingly, since the subject photographed from the direction of the photographing device 62, the subject photographed from the direction of the photographing device 64, and the subject photographed from the direction of the photographing device 66 can be seen, a stereoscopic image can be displayed.

  As described above, in the stereoscopic video display device 50 according to the present embodiment, as shown in FIG. 6, the right-eye video (that is, the B signal video) configured in blue and the left configured in red. In three consecutive parallax images composed of an eye image (that is, an R signal image) and an intermediate image composed of green (that is, an G signal image), a right eye image and an intermediate image Is distributed to the right eye, and a left-eye image and an intermediate image are distributed to the left eye, thereby displaying a stereoscopic image.

  In the above description, the B signal image and the G signal image are distributed to the right eye, and the R signal image and the G signal image are distributed to the left eye. As described above, the present invention is not limited to this. The right-eye video is an image of one signal in the RGB signal, the left-eye video is an image of one signal of the remaining two signals in the RGB signal, The intermediate video is distributed as the image of the remaining one of the RGB signals, the right-eye video and the intermediate video are distributed to the right eye, and the left-eye video and the intermediate video are distributed to the left eye. I just need it.

  That is, the stereoscopic image display apparatus according to the present embodiment includes three consecutive parallax images composed of only three different primary colors, and includes a first image, a second image, and a third image. In three parallax images in which two images are located between the first image and the third image, one of the first image and the third image is distributed to the right eye, and the other is distributed to the left eye. What is necessary is just to illuminate and distribute the second image to both the right eye and the left eye.

  Even when there are a plurality of observers, it is possible to display a stereoscopic image for each observer by capturing an infrared light image for each observer and displaying a binarized image for each observer.

  In the above configuration, the video shot by the shooting system 60 has been described as being displayed on the display device 80 by the display control device 70. However, the video shot by the shooting system 60 is recorded on a recording medium, and this recording is performed. The video information recorded on the medium may be played back by a playback device having the function of the display control device 70. That is, it is possible to display a stereoscopic video by recording the B signal, the G signal, and the R signal for each frame constituting the moving image and reproducing each signal by the reproduction device.

  In this embodiment, the three consecutive parallax images composed of only three different primary colors are composed of a first image, a second image, and a third image, and the second image is the first image. In the three parallax images located between the first image and the third image, one of the first image and the third image is distributed to the right eye, and the other is distributed to the left eye. Any other configuration may be used as long as the image is distributed to both the right eye and the left eye. For example, in the above example, the infrared light image of the observer reflected by the mirror 120 via the large convex lens 110 is used. However, the observer may be directly photographed by an infrared camera from the outer peripheral position of the display device 80 or the like. Further, instead of the infrared camera 140, a normal video camera may be used, and the light source 100 may also output visible light. Also, a front image is obtained by photographing from the front instead of a half image of the observer, and a signal corresponding to the right eye image and a signal corresponding to the intermediate image are displayed in a half area of the front image. However, a signal corresponding to the left-eye image and a signal corresponding to the intermediate image may be displayed in the other half of the area. That is, in the backlight division method in the optical method as described above, the display device has three consecutive parallax images composed of only three different primary colors, that is, a right-eye video signal, an intermediate video, and a left Displays a video signal for the eye, and the backlight displays a backlight corresponding to the right-eye video signal and the intermediate video at a position corresponding to at least the right eye, and at least a position corresponding to the left eye for the left eye A stereoscopic video can be displayed by displaying a backlight corresponding to the video signal and the intermediate video.

  In the description of each of the above embodiments, the imaging systems 10 and 60 have been described as obtaining three parallax images using three imaging devices. However, the present invention is not limited to this, and two imaging devices are used. Thus, a stereo image may be obtained, and for the intermediate image, a third image may be generated from the stereo image to obtain three parallax images. In this case, the intermediate video can be obtained by obtaining a morphing image of the video obtained by the two photographing devices.

  That is, in the first embodiment, the photographing / intermediate image generation apparatus 210 shown in FIG. 10 is used instead of the photographing system 10, and in the second embodiment, the photographing / intermediate image generation shown in FIG. Let it be device 210.

  The imaging / intermediate image generation apparatus 210 illustrated in FIG. 10 will be described. The imaging / intermediate image generation apparatus 210 includes an imaging apparatus 212, an imaging apparatus 216, an intermediate image generation section 220, an extraction section 232, and an extraction section 234. And an extraction unit 236.

  Here, the imaging device 212 has the same configuration as the imaging device 12 and the imaging device 62 except that RGB signals are output, and the imaging device 216 except for the point that outputs RGB signals, the imaging device 16 and the imaging device 66. It is the same composition as.

  That is, the configuration and positional relationship between the imaging device 212 and the imaging device 216 are the same as those in the first and second embodiments, and the imaging device 212 and the imaging device 216 are stereo when a human visually recognizes an object. The installation position and the shooting direction at the time of shooting are set so that an image can be obtained. Further, the distance between the center position of the photographing lens of the photographing device 212 and the center position of the photographing lens of the photographing device 216 is substantially equal to the distance between the human eyes. Thereby, it can be said that the video image | photographed with the imaging device 212 and the imaging device 216 is two continuous parallax images. Further, the video obtained by the imaging device 212 is a right-eye video, and the video obtained by the imaging device 216 is a left-eye video. Note that the photographing device 212 and the photographing device 216 are configured to photograph the same object. For example, when photographing a subject with the photographing device 212, the orientation and focal length of the photographing device 216 are automatically set from the orientation and focal length of the photographing lens of the photographing device 212. Further, both the photographing device 212 and the photographing device 216 output a color image, that is, an RGB signal.

  The intermediate image generation unit 220 generates an intermediate image of the RGB signal video output from the imaging device 212 and the RGB signal video output from the imaging device 216. When the intermediate image is generated, for example, a morphing image of an RGB signal image output from the image capturing device 212 and an RGB signal image output from the image capturing device 216 is generated. That is, a morphing image of the right-eye video and the left-eye video is generated.

  The extraction units 232, 234, and 236 extract predetermined signals from the input RGB signals. For example, the extraction unit 232 extracts the B signal from the video signal output from the imaging device 212, the extraction unit 234 extracts the G signal from the video signal output from the intermediate image generation unit 220, and the extraction unit 236 includes the imaging device. The R signal is extracted from the video signal output from H.216. Of course, the timing at which the extraction unit 232, the extraction unit 234, and the extraction unit 236 output signals is synchronized.

  The signal output from the photographing / intermediate image generation device 210 is sent to the display control device 20 in the first embodiment, and is sent to the display control device 70 in the second embodiment.

  In the first embodiment, when the configuration of the imaging / intermediate image generation apparatus 210 instead of the imaging system 10 is the first modification of the first embodiment, the other configurations in the first modification of the first embodiment are as follows. Since it is the same as that of the said Example 1, detailed description is abbreviate | omitted.

  The operation in the case of the first modification of the first embodiment will be described. When the imaging device 212 captures an image for the right eye, this image signal (RGB signal) is sent to the extraction unit 232 and an intermediate image generation unit. 220. In addition, when the imaging device 216 captures an image for the left eye, this image signal (RGB signal) is sent to the extraction unit 236 and also to the intermediate image generation unit 220. The extraction unit 232 extracts and outputs the B signal, and the extraction unit 236 extracts and outputs the R signal. The intermediate image generation unit 220 generates an intermediate image of the right-eye video and the left-eye video, and sends the intermediate image to the extraction unit 234. Then, the extraction unit 234 extracts and outputs the G signal.

  Subsequent operations are the same as those in the first embodiment. That is, the display control device 20 controls the display of each signal output from the photographing / intermediate image generation device 210 for each pixel in the same manner as in the first embodiment, and displays the signal on the display device 30. Thereby, the video displayed on the display device 30 is a color video composed of the B signal, the G signal, and the R signal, but the B signal, that is, the blue light is a video shot from the direction of the imaging device 212. The G signal, that is, green light is an intermediate image composed of a right-eye image and a left-eye image, and the R signal, that is, red light, is an image taken from the direction of the photographing device 216.

  When the observer visually recognizes the image displayed on the display device 30 through the complementary color glasses 40 having the above-described configuration, the left eye can see the R signal and the G signal, and the right eye can see the B signal and the G signal. be able to. Thereby, a three-dimensional image can be displayed.

  In the above description, it has been described that the extraction unit 232 extracts and outputs the B signal, and the extraction unit 236 extracts and outputs the R signal. The signal may be extracted and output, and the imaging device 236 may extract and output the B signal.

  In the second embodiment, when the configuration of the imaging / intermediate image generation device 210 instead of the imaging system 60 is the first modification of the second embodiment, the other configurations in the first modification of the second embodiment are as follows. Since it is the same as that of the said Example 2, detailed description is abbreviate | omitted.

  The operation in the case of the first modification of the second embodiment will be described. When the imaging device 212 captures an image for the right eye, this image signal (RGB signal) is sent to the extraction unit 232 and an intermediate image generation unit. 220. In addition, when the imaging device 216 captures an image for the left eye, this image signal (RGB signal) is sent to the extraction unit 236 and also to the intermediate image generation unit 220. The extraction unit 232 extracts and outputs the B signal, and the extraction unit 236 extracts and outputs the R signal. The intermediate image generation unit 220 generates an intermediate image of the right-eye video and the left-eye video, and sends the intermediate image to the extraction unit 234. Then, the extraction unit 234 extracts and outputs the G signal.

  The subsequent operation is the same as that of the second embodiment. In other words, the display control device 70 controls the display of each signal output from the photographing / intermediate image generation device 210 for each pixel in the same manner as in the second embodiment and displays the signal on the display device 80. Thereby, the video displayed on the display device 80 is a color video composed of the B signal, the G signal, and the R signal, but the B signal, that is, the blue light is a video shot from the direction of the imaging device 212. The G signal, that is, green light is an intermediate image composed of a right-eye image and a left-eye image, and the R signal, that is, red light, is an image taken from the direction of the photographing device 216.

  On the other hand, when an infrared ray is irradiated to the observer from the light source 100, the infrared light image of the observer is reflected by the mirror 120 and photographed by the infrared camera 140. The infrared camera 140 captures the captured infrared light. An infrared light video signal is output to the display control device 150 based on the image, and the display control device 150 performs display control of the backlight light source 160 based on the infrared light video transmitted from the infrared camera 140. That is, the display control device 150 displays the binarized image for the right eye and the binarized image for the left eye on the backlight light source 150 in the same manner as described above, and binarization for the right eye is performed at the time of the display. When displaying the image J1, two predetermined signals in RGB are displayed, and a signal corresponding to the right-eye image and a signal corresponding to the intermediate image are displayed. For example, when the video signal for the right eye is a B signal, the intermediate video signal is a G signal, and the video signal for the left eye is an R signal, the B signal and the G signal are displayed for the display area of the binary image J1. Display for each pixel. Further, when displaying the binarized image J2 for the left eye, two predetermined signals in RGB are displayed, and a signal corresponding to the image for the left eye and a signal corresponding to the intermediate image are displayed. For example, when the video signal for the right eye is a B signal, the intermediate video signal is a G signal, and the video signal for the left eye is an R signal, the R signal and the G signal are displayed for the display area of the binary image J2. Display for each pixel.

  Then, only the right eye image and the intermediate image are visible to the observer's right eye. In the above example, since the color image displayed on the display device 80 is viewed through the B and G signals, that is, the blue and green backlights, the right eye displays on the display device 80. Only the B signal and the G signal, that is, the blue color and the green color can be visually recognized. On the other hand, only the left eye image and the intermediate image are visible to the observer's left eye. In the above example, the display by the R signal and the G signal, that is, the color image displayed on the display device 80 is viewed through the red and green backlights. Only the R signal and the G signal, that is, the red color and the green color can be visually recognized. Therefore, since the subject photographed from the direction of the photographing device 212, the subject photographed from the direction of the photographing device 216, and an intermediate image thereof can be seen, a stereoscopic image can be displayed.

  Even when there are a plurality of observers, it is possible to display a stereoscopic image for each observer by capturing an infrared light image for each observer and displaying a binarized image for each observer.

  In the above description, the extraction unit 232 extracts the B signal, the extraction unit 234 extracts the G signal, and the extraction unit 236 extracts the R signal. However, in the first embodiment, the extraction unit 232 extracts the B signal. As long as the unit 234 extracts the G signal, the extraction unit 232 may extract the R signal and the extraction unit 236 may extract the B signal. In the second embodiment, the extraction unit 232 extracts one of the three types of RGB signals, and the extraction unit 234 is a signal other than the signal extracted by the extraction unit 232 of the three types of RGB signals. The extraction unit 236 may extract any signal other than the signals extracted by the extraction unit 232 and the extraction unit 234 from the three types of RGB signals.

  In the above configuration, an intermediate video is generated from video captured by the imaging device 212 and the imaging device 216, and the right-eye video, the left-eye video, and the intermediate video are displayed on the display devices 30 and 80. As described above, the video imaged by the imaging device 212 and the imaging device 216 is recorded on a recording medium, and the video information recorded on the recording medium is stored in the intermediate image generation unit 220 and the extraction units 232, 234, and 236. You may make it reproduce | regenerate with the reproducing | regenerating apparatus which has a function. That is, for each frame constituting the moving image, the RGB video signal for the right eye and the RGB video signal for the left eye are recorded, and the playback device generates the intermediate video and the video signal for the right eye. 3D video can be displayed by reproducing the video signal for the left eye and the intermediate video signal by the reproduction device. By doing in this way, it becomes possible to display a stereo image using a normal stereo image.

  Note that the configurations of the intermediate image generation unit 220 and the extraction units 232, 234, and 236 shown in FIG. 10 may be configured as devices having respective functions, or configured by software having the functions of the respective units. May be.

  In addition, in the above-described embodiments and the modified examples of the embodiments, when the color of the subject photographed by the photographing systems 10 and 60 is only one of RGB, for example, all the subjects are composed of only the R signal and are red. In some cases, since only the R signal is displayed in the video of that portion, the R signal is only visually recognized by the right eye or the left eye, and nothing is seen by the other eye. I can't. This applies not only to the R signal but also to the B signal and G signal.

  Therefore, in the display control devices 20 and 70, after a predetermined amount of color tone is shifted in the white direction with respect to a signal (RGB signal in this case) sent from the photographing device, the B signal, the G signal, and the R signal are respectively transmitted. It is preferable to extract and control display on the display devices 30 and 80.

  That is, in the first embodiment, the photographing / transition processing device 310 shown in FIG. 11 is used instead of the photographing system 10, and in the second embodiment, the photographing / transition processing device 310 shown in FIG. And

  The imaging / transition processing device 310 illustrated in FIG. 11 will be described. The imaging / transition processing device 310 includes an imaging device 312, an imaging device 314, an imaging device 316, a transition processing unit 322, a transition processing unit 324, and a transition. A processing unit 326, an extraction unit 332, an extraction unit 334, and an extraction unit 336 are included.

  Here, the configuration of the imaging devices 312, 314, and 316 is the same as that of the imaging devices 12, 14, and 16 and the imaging devices 62, 64, and 66 except that each imaging device outputs RGB signals. That is, the configurations and positional relationships of the imaging devices 312, 314, and 316 are the same as those of the imaging devices 12, 14, and 16 and the imaging devices 62, 64, and 66. In other words, the photographing device 312 has the same configuration as the photographing device 12 and the photographing device 62 and is for photographing a right-eye image. The photographing device 316 has the same configuration as the photographing device 16 and the photographing device 66, and is for photographing a left-eye image. The photographing device 314 has the same configuration as the photographing device 14 and the photographing device 64, and is for photographing an intermediate image between a right eye image and a left eye image. Further, each of the photographing devices in the photographing devices 312, 314, and 316 outputs RGB signals, unlike the photographing devices 12, 14, 16, 62, 64, and 66. That is, all three types of RGB signals are output.

  In addition, the transition processing units 322, 324, and 326 perform processing for transitioning the color tone of the RGB signal, which is the video signal output from the imaging device, in the white direction by a predetermined amount (see FIG. 12). That is, the transition processing unit 322 performs a transition process for the color tone on the RGB signal output from the imaging device 312, and the transition processing unit 324 performs the transition process for the color tone on the RGB signal output from the imaging device 314. The transition processing unit 326 performs a transition process on the color tone of the RGB signal output from the imaging device 316. In the transition processing units 322, 324, and 326, the amount of transition is the same. It should be noted that the amount of transition of the color tone is not limited as long as it can be a signal that slightly includes the other two colors even when the subject color is only one of RGB. It is necessary to set the transition amount so as not to be white. For example, in FIG. 12, when a certain subject consists of only the R signal and is at the position of Q1 in FIG. 12, the color tone is shifted in the white direction by a predetermined amount S with respect to the RGB signal. It shows that it becomes a position. The position of Q2 indicates that the color tone includes most of the red (R) component, but also includes the green (G) component and the blue (B) component.

  In addition, the extraction units 332, 334, and 336 extract a predetermined signal from the video signal that has undergone transition processing by the transition processing unit. For example, the extraction unit 332 extracts the B signal from the video signal output from the transition processing unit 322, the extraction unit 334 extracts the G signal from the video signal output from the transition processing unit 324, and the extraction unit 336 performs the transition process.
